Be -it known 'that I, CHARLES A. Coon,l

My invention has for one of its object the provision 'of mechanism' for performingthe ironing oft clothes, etc., with the least encumbrance owing to the absence of velectr1c cords which have heretoforey been continuously connected directly to theI iron, when the iron was being used. A further'object is that Jthe operator is never in danger of receiving a shock because there is no energy flowing into the iron when in use. v

My invention will be better understood by reference to the accompanying drawing, in which,-

Figure 1 is a top viewlof the stand showing certain features'of my invention.

Figure 2 is an elevation View of the parts 4shown in Figure 1, with some of the mechanism shown in cross section. l Figure 3 is a view similar to Figure 2,' and showing a fiat iron. in place, and the electric' energy flowing through the heating element of the iron.

Figure 4 is a sectional view taken on line 4 4 of Figure 2.

Figure is-a partialend view of the flat iron, showing the two terminal springs which are connected to the heating element.

lThe Hat-'iron Istand comprises a pl'ate 6 provided with a forward support 7 and side supports 8 8; said supports 8 8 extend above the plate 6 a short distance and provide means in conjunction with the lug 9, which is recessed at 10, to facilitate the placing of the electric fiat iron 11.

When the iiat iron is placed upon the plate, a, switch 12 is automatically closed so as to include the heating element 13' in circuit. This switch is referably made of two metallic switch blades 14 and 15 separated oy a block of insulation 16 and pivoted by pins or screws 17 and 18 to thev side SDtate walls and 20, respectively, also of insulating material, such as hard rubber or fiber.' VA top connecting wall 21 carries a central partition 22, which is also of insu-4 lating tmaterial, which serves to provide slots through which the blades 14 and 15 swing. The blades 14 and 15-are connected by means of an insulation pin 23, to which one end of a helical spring 24 is fastened, the other end of which is secured to arear wall 25 of the housing for'the switch.

Normally the switch is held in a retracted position, as shown in Figure 2, with contacting faces 26 and 27 of the switch blades 14and 15, respectively, drawn back so as to prevent accidental .-bridging of the two lades. In this position, the -uptnrned portion 28 of the block 16 projects above the surface of the plate 6 and is in position to be depressed by the use of the flat ironll. The plate 6 is formed with a'protecting housing 29 below the switch 12.

When the user of the flat iron places it l upon the plate 6, the pointed or forward part of the iron is first inserted in the recess 10 and then the rear part is dropped between the lugs 8 8 and into contact with the portion 28. which causes. the contacting facesI 26 and 27 of the blades 14 and 15 to .A swing into'engagement with the terminal springs 32 and 33 carried on aninsulating block 34 on the Hat iron, these sprlngs being connected to the terminals of the heatin element 13. kSince the blades are suitab y connected by leads-35 and 36 to a source of energy 37, the element 13 and the fiat ironwill be electrically heated to a suitable tem erature. Y

vy invention provides a at ironl and a simple means for causing an vautomatic electric connectionJtobe made to lthe flat iron in: order tofheat the same, and obviates the necessity of turning the iron on' end during the short intervals of non-usage, vas is customary. The user is also not encumberedI by electric cords, which often interfere with proper employment ,of an electric at-'iron.

It is apparent that changes and modifications can be made without departing from the s irit and scope of my invention.

I c aim:

1. In combination, an electric flat ironhaving two terminals a heating stand therefor, a switch rotatably supported on a sta- -tiona engage said terminals, a member rigidly secured to said blades and normally positioned to be engaged by the bottom 'surface of the fiat ,iron placed on the stand, whereby said switch is rotated' and said blades caused to engage said terminals. y

2. In combination, an electric Hat iron having two terminals, a heating stand therefor, a switch on said stand, )said switch comprising two blades varranged side by Aside and pivotally supported intermediate their ends on' a stationary part of said stand, the

upper ends of said blades being movable' into-contact with said terminals as the blades are rotated about their point of pivotal Support, a member rigidly secured to the lower ends of said blades and normally positioned to be engaged and moved by the bottomsurface ofa fiat iron placed on said stand,

whereby said blades are' automatically rotated into engagement with said terminals.

3. In combination, an electric flat iron having two terminals, a heating' stand there- Vfor having a surface on which* the bottom' of the iron is adapted to rest, a switch rotatably supported on ai stationary part of .v said stand and comprising two blades hav- 30 part' of said stand andcompr'ising'v two b ades having contact ends, adaptedY to whereby said blades are automatically rotated into engagement with said terminals.

4. In combination, an electric lat iron having two terminals, a heating stand therefor, a switch rotatably supported on a station'ary part of said stand and comprising two blades having contact Vends adapted to engage said terminals, a member rigldly secured to said blades and normallypositioned to be `engaged by the bottom surface of the flat iron placed on the stand, wherebysaid. switch is rotated and said blades caused to engage said terminals, and yieldablemeans vfor maintaining said memberl in position to be engaged'by the iron'placed on the stand..

5. In combination, an electric at iron having two terminals therein, a heating stand therefor having asurface upon which the bottom ofthe iron is adapted to rest, a casing on said stand, a switch arranged in said casing and rotatably supported on a stationary part of said stand, said casing havin an openingor each of said blades, said 4b ades having contact portions on their upper ends adapted to be moved through said openings and into engagement with said terminals as said switch is rotated, a member rigidly secured to the lower ends of said blades and having a part normally positioned above said surface 'on the stand and.

in positionto be engaged by the bottom sur- `face of the atiron placed on the stand,

whereby said switch -is rotated and said blades automatically brought into with said terminals.
